Pliant Therapeutics is a clinical-stage biopharmaceutical company and leader in the discovery and development of novel integrin-based therapeutics. Based in South San Francisco, California, Pliant was founded in 2015 to develop therapeutics to modulate specific pathways upregulated or dysfunctional in certain diseases. Our approach involves developing novel integrin-based therapeutics to treat solid tumors and other diseases. Integrins are a crucial link between a cell's internal structure and its external environment and function in cell signaling, regulation and adhesion as well as wound healing and immune response. Founded by a team of world-renowned researchers from the University of California, San Francisco, this group discovered key insights into the integrin biology and developed small molecule therapeutics to target this devastating disease process. Launched in 2016 by Third Rock Ventures, a leading healthcare venture capital firm, Pliant has developed an industry-leading proprietary library of over 15,000 integrins that serve as a key driver to its portfolio. We believe our platform may be broadly applicable across multiple disease areas including delivery of drug payloads to cells utilizing integrin receptor-binding molecules as tissue-specific delivery and internalization mechanisms. Currently, Pliant is conducting a Phase 1 study of PLN-101095, a small molecule, dual-selective inhibitor of αvß8 and αvß1 integrins, that has shown encouraging clinical activity in the development of a treatment of immune checkpoint resistant solid tumors. #
